Limitations on Examining Process Core Files

MDB does not provide support for examining process core files that were
generated by a release of the Oracle Solaris operating system preceding
Solaris 2.6. If a core file from one operating system release
is examined on a different operating system release, the run-time link-editor
debugging interface (librtld_db) may not be able to
initialize. In this case, symbol information for shared libraries will not
be available. Furthermore, since shared mappings are not present in user
core files, the text section and read-only data of shared libraries may
not match the data that was present in the process at the time it dumped core.
Core files from Oracle Solaris x86 systems may not be examined on Oracle Solaris SPARC systems,
and vice-versa.
